CARROLL DALE CLIPFELL, OF REDWOOD FALLS, MINNESOTA.

AUTOMATIC SWINGING STACKER.

SPECIFICATION forming part of Letters Patent No. 620,016, dated February21', 1899.

Application filed June 14,1898.

To all whom it may concern.-

Be it known that I, CARROLL DALE CLIP- FELL, of Redwood Falls, in thecounty of Redwood and State of Minnesota, have invented a new andImproved Automatic Swinging Stacker, of which the following is a full,clear, and exact description.

My invention relates to an improvement in the straw-stackers attached tothreshing-machines of that class which are swung upon their pivots so asto deposit the straw in a circle.

My invention comprises the novel features hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a longitudinal sectional elevation on the line 1 l in Fig. 2through a portion of the threshing-machine and the stacker. Fig. 2 is atop plan view, the threshing-machine body being shown in section on theline 2 2 in Fig. 1. Fig. 3 is a rear elevation of the machine, showingthe automatic swinging mechanism, the stacker being in section on theline 3 3 in Fig. 1; and Fig. 4 is a rear elevation, partly in section,on the line 4 4 of Fig. 1. Fig. 5 is a perspective View showing the armcarrying the rack-bar by which the stacker is swung.

The threshing-machine body A may be of any usual construction. To therear end of said body and at its bottom is fixed a vertical pivot-shaft0, upon which the stacker swings. This shaft is placed centrally of thewidth of the threshing-machine and the stacker. The stacker B is of anyordinary construction and comprises a chute having belts thereonconnected with cross-slats, by means of which the straw is elevated. Aplate I is secured to the frame upon which the stacker is carried andlies just below the bottom of the threshingmachine body. This plate I ispreferably of a circular shape and is held in position beneath the bodyof the threshing-machine by a guide I.

The endless belt upon the stacker, and by which the straw is elevated,is operated in the following manner: A horizontal shaft H, similar inconstruction to that ordinarily used, is journaled in the lower end ofthe stacker.

Serial No. 683,394. (No model.)

This shaft carries the elevating-belts and at one end has a bevel-gearH, which meshes with a bevel-gear G upon the upper end of a verticalshaft G. To the lower end of this shaft is fixed a bevel-gear G, whichmeshes with a bevel-gear F on a horizontal shaft F. Asprocket-wheel-and-chain connection may be used between the shafts F andH instead ofthebevel-gears. TheshaftFismountedin bearings upon a frame Fwhich pivots about the vertical pivot-shaft O and extends in a radialdirection therefrom. At its inner end it is provided with a bevel-gearF, which meshes with the two bevel-gears D, the latter being mou ntedloosely upon the pivot-shaft C. The bevel-gears D are turned by a pinione, mounted upon a horizontal shaft E, which is fixedly secured in theframe and is rotated by means of a sprocket-wheel E, secured to theouter end thereof, and a chain E which is connected with any suitabledriving-wheel. Belts and pulleys may be used in place of the sprocketwheel and chain. With this driving means it is evident that the stackermay be swung upon its pivot in any direction desired without interferingwith its operation.

To the outer edge of the semicircular plate I is secured a frame J.(Shown in perspective view in Fig. 5.) This frame is secured to theplate I by means of bolts which pass through slots J by which the frameJ may have a slight adjustment toward and from the pivot-shaft O. Thisframe J carries a bar M, which is curved so as to form an arc of acircle with the pivotshaft 0 as a center. This bar M is provided withteeth upon its upper and lower edges and which also extend about theends thereof. The frame J also carries a guide or retaining bar J, whichis secured to a lower extension J 3 and surrounds the plate M at an evendistance therefrom. This forms a track for the roller K upon the shaftK, and thus holds the pinion K in engagement with the rack-bar N.

A laterally-extending shaft 0 is mounted on the machine and is providedwith a worm O, engaging a worm-wheel N, mounted upon alongitudinally-extending shaft ,N. The other end of the shaft N isprovided with a universal joint K to which is connected a swinging shaftK. The shaft K is provided with a pinion K, adapted to engage the teethupon the curved bar M, and this end of the shaft engages the guide orretaining bar J, so that the pinion is held steadily in engagement withthe rack-teeth upon the bar M. The shaft K is restrained, so as to swingin a vertical plane, by means of a guide L, which consists of two barslying one upon each side of the shaft and supported from the body of themachine. The swinging portion of the stacker may be operated at anyangle with the body of the separator.

For convenience in swinging the stacker by hand the shaft 0' is providedwith a crank 0 which may be removed when desired. In order to throw theswinging device out of operation at any time desired, the shaft 0 isrotated by means of a clutch connection P, which is operated by ahand-lever P. The toothed plate or rack M may be made of any lengthdesired, the length thereof determining the amount of swing given to thestacker and the number of teeth atits ends the amount of rest at the endof the swing. The plate M may be made removable from the frame J, asindicated in Fig. 4. When the plate M is changed, the guide-bar J'should be changed correspondingly. To the lower end of the stacker isattached a hood or apron B, which is adapted to catch the straw asdelivered from the machine. This hood or apron is made wider than thestacker, so as to make sure of catching all the straw, even when thestacker is swung to its limit at one side.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. An automatic swinging straw-stacker, comprising astraw-elevator pivoted at its lower end to swing horizontally, a curvedbar carried by the swinging stacker and having teeth upon its upper andlower edges and about its ends, an inclosing guide-bar also carried bythe swinging stacker, a shaft having a pinion engaging said curved bar,a pivotal driving connection, and means for limiting the swinging of theshaft to a vertical plane.

2. An automatic swinging straw-stacker, comprising a straw-elevatorpivoted at its lower end to swing horizontally, means for operating thesame, a curved bar carried by the swinging stacker and having teeth uponits upper and lower edges and about its ends, an inclosing guide-baralso carried by the swinging stacker, a shaft having a pinion engagingthe teeth of said curved bar, and a pivotal driving connection, andfixed vertical guides engaging the swinging end of the shaft andlimiting its movement to a vertical plane.

3. An automatic swinging straw-stacker, comprising an automatic swingingstraw-elevator pivoted at its lower end to swing horizontally, means foroperating the same, a curved bar carried by the swinging stacker andhaving teeth upon its upper and lower edges and about its ends, aninclosing guidebar also carried by the swinging straw-stacker, saidtoothed bar and inclosing guide being carried by a plate mounted uponthe stacker so as to be adjustable toward and from its pivot, a shafthaving a pinion engaging said toothed bar, and a pivotal drivingconnection, and means for limiting the swing of the shaft to a verticalplane.
